--- Comment #4 from Alan Modra <amodra at gmail dot com> ---
It looks like the invalid reads are all due to the bfd_close in
plugin_maybe_claim which frees bfd->filename and the bfd itself.
add_archive_element keeps pointers to the_bfd and the_bfd->filename in a
lang_input_statement_type linker script statement, which are then accessed in
script traversals. my_archive is *not* set for thin archives..
